' 4 claims. (C1. 139-198) l ...This invention relates to what are knownin the textile industry as carpet or open top, hand threading shuttlesas distinguished from automatic threading shuttles by the fact that theyarn package used in such shuttles unwinds from the inside instead offrom .the outside of a cop or bobbin and is held in place in a recess orcop cayity in the shuttle which; has side walls the inside faces of`which are usually serrated, and a bottom but an open top.

, There is usually an outlet eye orthread eye atwhat we will call thefront end of such a shuttle which passes through a side wall into therecess.

, In the past, it has been considered necessary to have'a cover whichmay or may not be more or less resilient, pivoted at the back end of therecess or the end away fromlthe frontor the shuttle eye end,rand of sucha character that its free end is bent to form a hook to engage a latchdevice member which is movable and may be of various characters such asshown in the patents to: Shand, No. 339,941 of April 13, 1886; Sergeson,No. 1,278,034 of September 3, 1918; Richardson, No. 1,510,861 of October7, 1924; Sergeson, No. 1,728,083 "of September 10, 1929; andSergeson,No. 2,071,238 of February 16,1937.

' `We have discovered that byusing a flat resilient cover ofsubstantially the same width throughout its'length and with `a free end,which is preferably rounded, to go under a holding pin extending acrossthe recess at the front end and having at the back end of the recess apivot part of substantially cylindrical form in which is a tightlyfitting resilient lining throughwhich a pivot pin is driven, such adevice will hold the yarn mass resiliently in place and can alsdbeeasily released from or engaged with the holding pin 'at the front end.The combinationvof the resiliency of the yarn mass, the cover itself andthe elastic lining, will allow the shuttle to operate in the loomwithout noise and without vibration, the whole construction being muchsimpler than any now in use.

Our resilient construction of the cover which rests upon thesubstantially resilient yarn package combined with our resilient lining,all cooperate to take up the shock which a shuttle is constantlyreceiving from the picker action. rAltogether they absorb this shock soas to prevent or greatly reduce the tendency, which is found in shuttlesof a similar type and for a similar 2 breaks not only do damage to ordestroy the usefulness of the shuttle itself but also cause enormousdamage to the warp when and if the broken parts of the cover project.

The elimination of numerous pivot parts, arms and so forth, greatlysimplies the construction, reduces the crystallizing points and servesthe desired purposes in a much better manner.

In the drawings, Fig. 1 is a top plan view oi a shuttle with a yarn orthread package resiliently held in place by our device.

Fig. 2 is an elevational View as from the eye side or bottom side ofFig. 1 with parts broken away and with the cover member shown in dottedlines as bent to release or lock its free end but without a threadpackage.

Fig. 3 is a broken side elevational View of a shuttle as from the pivot.end of the cover with a package held in running position.

Fig. 4 is a lateral vertical sectional View as on the line 4--4 of Fig.3.

The metal pivot pin H is driven through a closely tting hole in the woodand in the lining F so that the cover moves very slowly in pressing downon the yarn package as it tends to collapse as the yarn runs out fromthe inside. This also eliminates rattling.

The drawings represent a shuttle having a hollow body B in which is arecess R to receive a yarn package P made up of thread T, the packagebeing positioned in the recess R which has a bottom 3 and side walls 4and 5, the inside faces of which are serrated. There is a thread eye Ethrough which the thread T from a yarn package P passes, this eye beingnear the front of and passing through one side wall. The top of therecess R, shown as 8, is open.

For convenience, we will call the end of the recess and the shuttlewhere the eye is located, the front and the other end, the back.

A representsk a holding pin which extends transversely across the frontof the recess R near its top and preferably is positioned nearer theYfront of the recess than the eye E.

C represents a cover which is formed of a resilient material andcomprises a shank l0 which as shown, is of uniform width and thicknessand has at its front end Il a free tip I2 which, as shown, is curved andis intended to go under the holding pin A.

At its other or back end I3 cover C is curved around to form asubstantially tubular integral pivot member I4 `and inside of this, Weposition a resilient lining F of cylindrical form, preferably made of aresilient material such as rub- 3 ber, neoprene or even nbre, with apivot hole I through it, whereby pivot pin H can pass through the twowalls 4 and 5 of the recess and through this hole I5 of lining F, thusproviding a resilient pivot for a cover C near the back and top.

As shown, the bobbin recess R is extended at the frontttoforrn a holdingpin part 2|) with straight side walls 2|, 2| andwith ilatbottom |23. Thefront holding pin A, as shown, is driven through one side wall 4 acrossthis part of the reiV i cess and into the other side wall 5 above andover ilat bottom |23.

At the back bobbin recess R, isgexte/ndedltoY form a pivot pin part 23With'side walls 21,21; which are preferably a distancecapart, slightlygreater than the width of the cover C as are` also the side Walls 2| and2| of thezholdingT pin part 20. These walls keep cover C'lo'os butlaterally in place.

Extending through the side wall 4 is a two part pivot pinhole 24,v 25,which at,r Zllfv goes into pivot pin part 23 and thence as, a.A dead endpart 25' in thesde wall 5., There is.; also preferably a pivot pindrive` hole2 extending therefrom out through the side wall 5.

In assembling-.theparts; the resilient lining E is florced'finto thesubstantially cylindrical Dill-OtV member I4 at;the..end! of cover C andboth are placed vin position With lining hole I5 in therrlining with thepivotjpin, hole 24; 25, whereupon the pivot pin H is drivenithrough' thepart 24 of thepin hole in thewood; and throughhole |5- in., the. liningF andv into the` part 25.- of the pin hole` so. thatrit; fitsA all'y ofthem witha driver frictionfit.

The resiliency of lining E as ',wellfasthe, tight fitting into thewood othe; shuttle keeps f the pin. frorrr` coming out ofv hole; part withoutthe use of anyscrew. threads.nuts oranything of` that'kind'.v When itis. necessary. to replace a cover or a pin or any oth'erpartYV orwhen'the liningF loses its resiliency or. wears: down', a suitablesmallldrive pin is'4 pushed into, drivel pin hole 26`-and hammered untilthe pivotv pin H is driven out. The pinH, lining F orcover, C or any orall of them can then beA replacedby another or by other parts.l

To installafyarn package cover-' C is bent as shown in the dotted linesFigil 2, Aand its front end II and free end l2 are removed from betweenholding pin A and the bottom! i231lof recess part 28 so that the -wholecover can be swung out of the way. A newpackagecan now be put inposition andthe cover can be! swung down, bowed and its-end Ii pushedinunder pin A and over and on to bottomI23l.

As shown in Figs. 2 and-3-, the cover-C when bent over a yarn package Pand under holding pin A causes its end |2- to be held between holdingpin A and the bottom |23 of recessZU and its resiliency and theresiliency Aof -the solid resilient lining F keep all metal partsinplace and prevent any rattling or vibrating which would tend tocrystallize anyofth'e -m'etal'apar'ts We claim:
